Hi, so I updated my BIOS on my Hp ProBook 440 G3 computer and now I get a 4 Blink LED. I took it to a repairman near me and I described my problem, and he said it was a bad virus? If it's a "bad virus" can I just put a new hard drive in?

Try a hard reset. Remove battery and AC power and hold down power button 20 seconds; now connect AC adapter and turn on (or try to). If all you get is flashing LED the computer is not posting to where it is even initializing the hard drive. The repairman near you has misdiagnosed to be charitable...it seems more like a failed BIOS flash and if he were any kind of repairman he would be talking to you about emergency recovery of the BIOS. Post back if you want to discuss possibilities. But not looking good.

The fact that it happened right after a BIOS update tends to point toward BIOS. Did it boot at least once after the BIOS flash? If so it is not a bad BIOS flash and it may be the video which would essentially mean a new motherboard.

I tried what it said in the document, and I don't know what happened.... I plugged the USB in and did windows key and B and it did 2 blinks and the LEDs stopped blinking. No more blink codes. There's still no display on the screen though. Also it never booted after the BIOS update.
